How can I change the wall's thickness?

The default wall thickness in every new plan is 12 cm or 4.7". If you wish to change it, you should do it before you start drawing the walls. Click on the Settings and enter the new value. You can also choose to work in either centimetres or inches.

In case you need to draw walls with different thickness - for example, the external and the internal walls; then you can:
